The SLXD+ delivers transparent 24-bit digital audio with a wide dynamic range, keeping speech crisp and performances true to source. Low latency helps the system feel immediate on stage and in monitoring, reducing the sense of separation that can occur with some wireless setups. A selectable high-pass filter is available within the system processing, helping manage low-frequency handling noise and rumble when needed.
Stable RF across a wide K55 band
Designed for professional environments, SLXD+ supports a wide tuning range within the K55 band, giving you more freedom to find clear channels. Digital transmission helps maintain consistent audio in challenging venues, and the system is engineered for reliable operation at distance where conditions allow. Tuning step size is optimised for regional operation, supporting efficient frequency coordination.
ShowLink Ease remote control convenience
ShowLink Ease creates a dedicated control link between receiver and transmitter, enabling remote management of key wireless parameters. This includes adjusting transmitter gain, changing frequency when a cleaner channel is found, locking or unlocking controls, and even performing transmitter firmware updates. It is especially useful in installed systems, volunteer-run venues, and productions where transmitters are not easily accessible mid-show.
Secure, scalable, and ready for real gigs
Every SLXD+ system includes AES-256 encryption for secure wireless transmission, ideal for corporate, broadcast, and presentation use. The receiver’s rugged metal build suits touring racks and fixed installations, while the bodypack supports AA batteries or optional rechargeable Shure SB903 packs. With strong RF fundamentals and practical monitoring and control options, it’s built to be easy to deploy and dependable under pressure.
